The album "Briefcase Full Of Blues" signed on the front cover by John Belushi and Dan Aykroyd in blue Sharpie pen. The signatures were obtained by veteran collector John Morgan outside the NBC Studios in New York in 1979. The album is in overall very good shape, some splitting at spine. The vinyl record shows very minor scratching. Belushi's signature is rare in any form. In combination with Aykroyd, on their first and most successful Blues Brothers album, is probably the most desirable form.
